Quality and Durable Mixer Agitator Factory

SINOU mixer agitator is a customized top-entry vertical industrial stirring mixer developed exclusively for harsh concrete plant wastewater working conditions, focusing on solving bottom sediment hardening, uneven chemical agent mixing and poor water circulation balance existing in sewage reaction tanks, buffer tanks and dosing tanks.

Unlike general-purpose agitators sold on the market that only adapt to clean water mixing, this professional mixer agitator is upgraded aiming at high-alkali wastewater, desert fine sand and cement suspended sludge, adopting low-speed axial flow stirring mode without breaking sludge flocs.

It can operate stably 24 hours a day without shutdown, ensuring uniform water quality in the whole tank and improving the overall treatment efficiency of the supporting environmental protection system.

This mixer agitator is a necessary auxiliary stirring device matched with spray column, HDPE slurry pipe and heavy duty mixer truck washing machine, forming a complete closed-loop wastewater treatment stirring and conveying system for mixing stations.

Unique Fluid Mixing Working Principle

Many overseas project engineers raise the question: Why cannot high-speed stirrers replace professional low-speed mixer agitator for sewage sludge treatment?

High-speed stirring equipment will produce strong water shearing force, which will destroy the flocculent structure of settled sludge, leading to re-suspension of fine sediment and failure of subsequent sedimentation and filtration procedures.

Our SINOU mixer agitator adopts axial flow low-speed circulating stirring principle with gentle fluid pushing power, and the complete working flow is as follows:

(1) The waterproof vertical motor transmits stable power to the high-precision helical gear reducer to reduce output speed and amplify output torque;

(2) The integrated long stirring shaft drives double-layer axial flow impellers to rotate slowly vertically inside the sewage tank;

(3) The rotating blades push the tank bottom sludge to generate upward vertical water flow and surrounding horizontal circulating water flow;

(4) Eliminate all stirring dead corners at tank bottom, tank wall and liquid surface to prevent hard sludge crust;

(5) Realize full mixing of alkaline sewage and neutralization medicament, cooperate with overall water circulation pipeline to stabilize water inlet quality of subsequent spray column;

(6) Whole operation process has no water splash, no secondary sludge disturbance, and matches continuous working rhythm of mixing plant sewage stations perfectly.

Complete Structural Components & Material Details

All core parts of SINOU mixer agitator are selected and optimized targeting long-term erosion of alkaline sewage and sandy sludge, abandoning ordinary carbon steel vulnerable to corrosion, and each component has clear functional positioning:

● IP65 Fully Waterproof Vertical Motor

Adopt full enclosed waterproof and dustproof motor housing, suitable for outdoor humid and foggy sewage workshop environment. Support global dual frequency power supply 380V 50Hz / 380V 60Hz, compatible with unstable generator power supply widely used in Middle East desert construction sites. Optional explosion-proof motor for special waste gas enclosed workshops.

● Helical Gear Heavy-duty Reducer

Different from ordinary cycloidal reducers with high failure rate, helical gear reducer runs more smoothly, with stronger overload resistance. It can cope with instantaneous heavy load impact caused by sudden thick sludge accumulation at tank bottom, effectively protecting motor from burnout, with ultra-low noise and no oil leakage for long-term operation.

● One-piece Integrated Stainless Steel Stirring Shaft

Adopt SUS304 or upgraded SUS316L integrated seamless stirring shaft, no intermediate flange splicing. Avoid shaft swing, shaft vibration and shaft breakage caused by long-term rotation, greatly improving overall equipment stability.

● Axial Flow Large-area Curved Impeller

Adopt special axial flow blade instead of ordinary radial straight blade. It focuses on pushing overall liquid circulation rather than local liquid cutting, with larger stirring coverage area, stronger bottom sludge pushing force and lower energy consumption.

● Triple Independent Mechanical Seal System

Three-layer mechanical seal structure is installed at the shaft penetration position, which can effectively block sewage and fine sand from penetrating into reducer and motor, solving the most common water leakage and motor damage failure of traditional agitators.

● Integrated Tank-edge Fixed Bracket

Thickened carbon steel painted anti-rust bracket, integrated welding forming, directly fixed on tank top without tank body punching damage. Fast installation, firm fixation, free of overall displacement during long-term stirring vibration.

● Optional Frequency Conversion Control Cabinet

Match independent frequency converter to adjust stirring speed freely according to sludge concentration, realizing energy-saving operation under different working loads.

How to choose the right mixer agitator for your wastewater tank project?

Improper selection of mixer agitator will lead to incomplete stirring, frequent equipment stuck or excessive energy consumption. We sort out 5 targeted selection standards for engineering buyers to avoid matching errors:

(1) Confirm actual effective volume of the sewage tank first: select low-power small agitator for small dosing tanks, and match high-torque large model for large circulating sedimentation tanks;

(2) Measure the actual depth of the tank to customize accurate stirring shaft length, ensuring impeller is 300mm above tank bottom to avoid sludge collision;

(3) Judge water quality alkalinity: select SUS316L material for long-term strong alkaline sewage to extend service life;

(4) Check on-site power supply: confirm 50Hz or 60Hz power frequency to match corresponding motor parameters for Middle East overseas projects;

(5) Match overall system process: supporting spray column and large-scale water circulation system need to equip frequency conversion mixer agitator for intelligent speed adjustment.
